139678-43-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139678-43-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,7 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139678-43:
(8*1)+(7*3)+(6*9)+(5*6)+(4*7)+(3*8)+(2*4)+(1*3)=176
176 % 10 = 6
So 139678-43-6 is a valid CAS Registry Number.

Preparation method of moxifloxacin hydrochloride chelate

-

Paragraph 0021; 0027-0032, (2021/03/05)

The invention provides a preparation method of moxifloxacin hydrochloride chelate, and belongs to the technical field of heterocyclic compound preparation. The preparation method comprises the following steps: keeping excessive acetic acid, adding trimethyl borate into the acetic acid, and reacting at 110-120 DEG C; after the reaction is finished, cooling, adding gatifloxacin intermediate, heatingto 110-120 DEG C after the addition is finished, keeping on reacting; recovering the fraction under reduced pressure until the reaction is finished, and recovering the solvent until the solvent is dry to obtain the chelate. The method has the advantages of simple process, economy, environmental friendliness and high product purity.
